A foveated passive UHF RFID system for mobile manipulation
(Georgia Institute of Technology, 2008-09)
We present a novel antenna and system architecture for mobile manipulation based on passive RFID technology operating in the 850 MHz - 950 MHz ultra-high-frequency (UHF) spectrum. This system exploits the electromagnetic ...
RF vision: RFID receive signal strength indicator (RSSI) images for sensor fusion and mobile manipulation
(Georgia Institute of Technology, 2009-10)
In this work we present a set of integrated methods that enable an RFID-enabled mobile manipulator to approach and grasp an object to which a self-adhesive passive (battery-free) UHF RFID tag has been affixed. Our primary ...
Probabilistic UHF RFID tag pose estimation with multiple antennas and a multipath RF propagation
(Georgia Institute of Technology, 2008-09)
We present a novel particle filter implementation for estimating the pose of tags in the environment with respect to an RFID-equipped robot. This particle filter combines signals from a specially designed RFID antenna ...
RFID-Guided Robots for Pervasive Automation
(Georgia Institute of Technology, 2010-01-15)
Passive UHF RFID tags are well matched to robots' needs. Unlike lowfrequency (LF) and high-frequency (HF) RFID tags, passive UHF RFID tags are readable from across a room, enabling a mobile robot to efficiently discover ...
